My point that either submitter or maintainers may catch up the problem if at least there are means to report the problem. So I'm still thinking it's not a bad idea to add the warning message, maybe even for the "checkpatch --strict" option only. I'm not insisting that it is something super-necessary and it's up to you guys to decide in the end.
